I want to say that I'm not defending in any way the actions of Russia, but I just want to offer a possible explanation for their invasion of Georgia.
First, Georgia invaded South Ossetia, a pro-Moscow area who wants to break away from Georgia, to "control dissent" I'm sure. Russia's invasion was perhaps a response to this, as they wanted to support their contingents in S. Ossetia.
Second, Russia feels like the rest of the world is closing in on them. As Lisa stated briefly, the signing of a missile defense shield package between the US and Poland is seen as a direct threat to Russian security and interests in the area. A "missile defense shield" is just a fancy phrase for the fact that to stop an incoming missile, you shoot it with another one. Well guess what? Parking missiles in Poland, a neighbor of Russia, is the same as the USSR parking missiles in Cuba in 1962, right in the back door of the US. We responded to that with embargo's and the Bay of Pigs invasion. The similarities with Russia today are clear.
As one media reporter stated, Russia invaded Georgia to "take it's balls back." The Red Bear wants to show the world that it's still a force to be reckoned with, and lets face it, since the collapse of the USSR, Russia has been mostly ignored by the rest of the world. Pay no attention to the sleeping bear in the room folks, but guess what? The bear just woke up...and it's hungry.
Third, I can't discount the fact that just like the US invasion of Iraq, Russia did this for oil. The Baku-Tbilisi-Ceyhan (BTC) oil pipeline which runs through Georgia is seen as a threat to Russia's oil pipelines. It's shorter and probably cheaper to use. Why pump the oil through Russian pipes with you can do it through the Georgian pipeline? Russia even tried bombing the pipeline itself! Everyday that pipeline is in operation, the Russians are probably loosing a lot of money, money which I'm sure their struggling economy needs. I wouldn't be surprised if they also bombed it (and if they succeeded) to deny oil to the West in order to take it for themselves. Because, lets face it folks, we're in a long-term resource war. Every country is. I keep saying it and you know I have, but I'll say it again. Peak Oil. That is all.
